1x100 stranded total transcriptome preps; the insert size is variable; could be less than 100 bp. The linker sequence at the end of read will be ATCTCGTATGCCGTCTTCTGCTTG. Protocols: 100ng of total RNA was fragmentated, end repared and ligated with illumina small RNA v1.5 adaptors. The ligated RNA was reverse transcribed and PCR amplified with 15 cycles. The PCR product was normalized by DSN digestion and used for sequencing.
